SUPPORT FOR RING TRAVELERS.

Application filed January 16, 1928. Serial No. 247,014.

My invention relates to supports for ring travelers of the type whereinthe spinner or twister ring is reversible and horizontal, and thetraveler, circular.

At present a loose or broken thread carried by the operating spindlestrikes against the lubricant exposed upon the inner face of the ring,thus fouling the thread on the spindle bobbin, and sometimes spottingthe thread upon adjacent bobbins.

An object of my invention is to prevent the above disadvantages. Otherobjects of my invention are to insure a perfect inteiengagement of theparts, and permit a facile reversal of the ring, as well as aflord astrong construction.

My invention, therefore, consists in the means for effecting the resultsabove referred to.

In the accompanying drawings,

Figures 1 and 2 are a plan and a side elevation of my novel device,

Figure 3, a section of the same and a ring rail upon which it is mountedtaken on line 33 of Figure 1,

Figure 4, a detail view of the shield memher, and

Figure 5, a fragmentary enlarged section of a part of my devicecorresponding with Figure 3.

Similar reference characters indicate similar parts throughout theviews.

As herein shown 6 represents the ring rail of a spinning or twistingframe, and 7 one of the usual spindle orifices.

An annular ring holder 9 is vertically split, as at 10, to form aneXpa-nsible and contractible member comprising a flat annular head orrim 11, and a depending cylindrical body 12 integral with anintermediate portion of the head. The latter is provided in its upperface with an internal channel 13 forming a horizontal supporting face 14and an undercut or inclined bearing face 15. The resilient body 12 isfrictionally seated in the orifice 12 of the ring rail, and the exteriorportion of the rim 11 rests upon the latter. A hori zontal spinning ortwisting ring 17 comprises a base flange 18, an intermediate web or body19 and a flat head or flange 20. The flange 18 of the ring rests uponthe face 14 in the channel 13 and is slightly overlapped by the wall orface 15, and is tightly engaged therewith by the resiliency of theholder 9.

A tubular shield member 23 consists of a cylindrical lower portion 24whose exterior tightly engagesthe inner face of the body 12 of the ringholder, and an inwardly and upwardly tapering or retracted intermediateshoulder portion, terminating in an upper cylindrical neck or shieldportion 26 extending to substantially the top of thering 17, butlaterally spaced therefrom, so that there is an annular recess orraceway 28 intermediate the wall 26 and the flange 20 for a circulartraveler 30 upon said flange.

The lubricant upon the inner face of the port-ion 19 of the ring is thusshielded from contact with any loose or broken thread carried by thespindle or fed thereto from the delivery rolls through the traveler 30.

I claim 1. In a support for ring travelers, an annular ring holderprovided with a vertical split and with an internal channel in its upperface, a traveler ring seated in the channel and an imperforate tubularshield em-, braced by the holder and frictionally held therein andextending from the lower edge of the ring to approximately thehorizontal 30 plane of the ring top and spaced from the ring to form araceway for a traveler.

2. In a supportfor a ring traveler, a resilient annular ring holderprovided with a I vertical split, a traveler ring embraced by theholder, and a shield comprising a cylindrical lower portion alsoembraced by the ring, an inwardly and upwardly tapering intermediateportion, and a cylindrical upper portion extending to substantially themaximum height of the ring and spaced from the ring.

In testimony whereof I have afliXed my signature.

GEORGE H. GILLIGAN.
